This compound is widely utilized in bioconjugation and drug delivery systems due to its polyethylene glycol (PEG) chains, which enhance solubility and stability. The maleimide group allows for specific conjugation with thiol-containing molecules, such as cysteine residues in proteins or peptides, enabling the creation of targeted therapeutic agents. Its branched PEG structure improves pharmacokinetics by reducing immunogenicity and prolonging circulation time in the body. It is also employed in the development of antibody-drug conjugates (ADCs) and other bioconjugates, where precise attachment of therapeutic payloads is critical. Additionally, its water-soluble properties make it suitable for use in nanotechnology and as a linker in diagnostic imaging agents.
